Unlock the full potential of the Arduino Uno Q, the most powerful and versatile Uno ever created.

The Arduino Uno Q isn’t just another microcontroller; it’s a powerhouse on a single PCB. Featuring a dual-processor architecture, it combines a quad-core ARM A55 running Linux with an STM32 running the Arduino Core on top of the Zephyr RTOS. This unique combination gives you the high-level networking and processing power of a computer alongside the real-time, pin-accurate control of a professional IoT device.

Programming the Arduino Uno Q is your essential guide to mastering this sophisticated hardware. Written for programmers and electronics enthusiasts who want to move beyond simple "copy-paste" sketches, this book focuses on the "how" and "why" of the STM32 side of the board.

What You Will Learn:

• Deep Hardware Control: Master the STM32's GPIO lines for precise interaction with sensors, servos, and motors.

• Professional Protocols: Get hands-on with PWM, SPI, I2C, and the 1-Wire bus.

• The Power of Zephyr: Learn how to use the Zephyr real-time operating system to handle asynchronous processing and advanced drivers.

• Hardware Configuration: Understand how to use the Devicetree to customize and augment the Arduino Core.

• The Processor Bridge: Discover how to make the ARM A55 and STM32 talk to each other, using Python on Linux to control C programs on the Arduino side.

A Deep Dive, Not Just a Project Collection

This is a conceptual guide designed to build your skills from the ground up. Instead of just following instructions to build a single gadget, you will acquire the foundational knowledge needed to architect your own professional-grade IoT solutions. By the time you reach the final chapter, you will have moved past trial-and-error coding and into the realm of confident, professional development.

Harry Fairhead has a background in electronics as well as programming andis the author of many books about the Internet of Things both for the hobbyist and the professional, the most recent being Programming the ESP32 in C Using the Arduino Library. C is his programming language of choice and he is the author of Fundamental C: Getting Closer To The Machine and Applying C For The IoT With Linux. His other IoT books target all members of the Raspberry Pi Family of devices - including the Raspberry Pi 5, CM5, and Pico 2W - as well as the ESP32, with Python versions co-authored with Mike James.
